This invention relates to the mechanismi for driving 'the ram o'f'a shaping machine,- although 'thejprm'ciple s capable of general usewhe re rotary motion is to be convertedproved lubricating'device therefon I n y f The invention also involves'improvements infcombmatlons ofpartsand m (161321.118 of" into reciprocating motion.

The principal objects of the invention are to fpr'ovide a su pportforthe driving crank.
